The sum of the areas of the three sides of the cube is 50 cm squared. find the sum of the lengths of all edges of the cube.

Knowing that the sum of the areas of the two faces is 50 cm squared, you can find the length of the edge of the cube.

The area of one face is 50/2 = 25, since the area of the square is S = a ^ 2, we extract the root of 25, we get the length of the edge of the cube – 5 cm. Since there are 12 edges in the cube (four – top, bottom and side), we get the result:

12 * 5 = 60 cm

Answer: The length of all the edges of the cube is 60 cm.
